Laser Processing of Metallic and Intermetallic Surfaces

Abstract

The most common applications 01 the laser processing 01 metallic and intermetallic surfaces are presented. The advantages 01 this technology are deduced Irom the basic principles 01the interaction 01laser light w"h metallic materials. Applicetions, like superficial hardening and surface cleaning and alloying, are extensions 01 exi:rting processes beneming by the specific advantages 01laser annealing. Other ones, like de,position 01 passivating or wear·resistant coatings, exploit photochemical reactions induced in gas-phase or at metallic and semiconducting surfaces by UV or high intens"y laser beams.

3D-MID Technology for Surface Modification of Polymer-Based Composites: A Comprehensive Review

“…In order to work with LDS method, usable plastics for LDS required specific additives such as Cu 2 O, CuO or CuCl 2 , which can be added in a very high concentration to the blend during compounding step. The characteristic of these additives is extreme heat resistance and great potential to prevent nucleation during injection molding process [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. However, it is also possible to prepare plastics for LDS without specific additives.…”

“…LDS is based on the principle of ablation and nucleation by using laser irradiation. Therefore, the laser patterning creates a microscopically rough surface and simultaneously activates the specific additives that are necessary for the metallization step [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. The schematic of LDS method is illustrated in Figure 1 .…”
